Description

Description of the Industrial Invention having for title: “Card transport device for card-reading devices card processing and device card processing including the said transport device” in the name of: MATICA FINTEC SPA of nationality Italian, with headquarters in Via G. Parini, 9 20121 Milan (ME). Designated Inventor: Pier FRANCESCUTTI Filed under no. DESCRIPTION The present invention relates, in general, to a card transport device for card processing devices and to a card processing device comprising called transport device. In particular, the invention relates to a transport device for CR 80 format cards or cards according to ISO 7810, e.g. cards bank, identity documents or similar for a printing unit, such as inkjet. Devices of this type are known in the art. transport of cards for treatment devices of the cards, in which the card is personalized -1- by treating its surface, for example example by inkjet printing which may be preceded by plasma treatment to make its surface more receptive to the ink. These known card transport devices They generally use rubber rollers to paper feed and guides to direct it; These rollers and guides act on the surface of the paper to be treated and can cause problems on the quality of the printing process, depositing debris on the surface of the paper to be treated present on the rollers, which can form during previous works or can be left by previously treated cards, or causing scratches with the guides sliding on the surface of the paper. The purpose of this invention is to solve the above-mentioned technical problems front, providing a carrying device cards for card processing devices and to a card processing device comprising said transport device which are reliable and allow you to print the cards with high quality without deteriorating their -2- surface during paper transport. The above and other purposes and benefits of the invention, as will result from the following of the description, are achieved with a card transport device for card-reading devices card processing and a device card processing including the said transport device such as those described in their respective independent claims. Forms of favorite realizations and non-trivial variations of the present invention form the object of the dependent claims. It is understood that all claims attached form an integral part of this document. description. It will be immediately obvious that one can make countless variations to what has been described and changes (for example relating to shape, size) sions, arrangements and parts with equi- functionality (valid) without departing from the protection field of the invention as it appears from the claims attached. The present invention will be better described from some preferred embodiments, provided by way of example and not limitation, with -3- reference to the attached drawings, in which: - Figure 1 is a schematic view in perspective of a transport device cards according to the present invention; - Figure 2 is a schematic top view of a card transport device according to the present invention; - Figure 3 is a schematic view of a detail of a transport device cards according to the present invention; - Figure 4 is a schematic view of a detail of a transport device cards according to the present invention; - Figure 5 is a schematic view in perspective of a transport device cards according to the present invention. Referring to the Figures, the 100 card transport device for devices of card processing in accordance with this invention includes: - at least two 11 friction feed rollers configured to act on a first edge 31 of the paper 30, preferably one edge of the side of greater length of paper 30, called rollers of 11 clutch advancement are motorized, to -4- example in a known way via an electric motor 25, and have respective rotation axes 26 parallel to each other and substantially perpendicular to a direction XX and to a progress plan of a card 30; said feed rollers 11 a clutches are configured to exert a pressure on the first edge 31 of the paper 30, in particular with their lateral surface 5, for advance the card 30 without touching its surface to be printed 50 so as not to contaminate it and not damage it, - elastic contrast media 21, 22 configured to exert pressure, especially with the their lateral surface 6, on a second edge 32 of card 30, opposite the first edge 31, keeping the paper 30 in contact with the rollers 11 friction advance; preferably, the means elastic contrast rollers include at least two rollers of contrast 21 having rotation axes 24 parallel to the rotation axes 26 of the rollers advancement 11, and pressure means 22, for example springs, which exert pressure on the rollers contrast 21, for example on their axes 24 or on a support 23 connected to said axes 24, for keep the paper 30 in contact with the rollers -5- advance 11 to clutch and advance it in the direction XX on the paper feed plane 30 in the card processing device; so preferred two feed rollers 11 and / or two rollers of contrast 21 adjacent are mounted to a distance such as to keep them simultaneously at card contact 30. Preferably rollers 11, 21 are made in metallic material or technopolymer, and the axes 24 and support 23 are sliding in one direction perpendicular to the direction XX of paper advancement 30 under the action of the means pressure 22 to press the contrast rollers 21, in particular their lateral surface 6, on the second edge 32 of card 30. In a preferred embodiment of the invention, the lateral surface of the rollers 11, 21 includes a “V” shaped throat 5, 6 to make advance the paper 30 by applying pressure on the corners 41, 42 of its edge, on the line of contact between the edge 40 and the surface 50 of the card 30. Preferably, throat 5, 6 has two surfaces 51, 61 arranged in a “V” shape, each forming an angle α of 45°, preferably between -6- 40° and 50°, with respect to the feed surface of the 30 paper in the treatment device cards. Preferably, the device 100 of card transport and processing device of the cards in accordance with the present invention are operated by known type of operating means, comprising for example at least one electric motor 25, and piloted by a control unit as well Note. Preferably, the device 100 of card transport according to the invention is used in a card processing device that is an inkjet printer (ink- jet), but can also be used in other card processing devices such as devices for magnetic writing and / or “encoding” of the chip or the magnetic stripe of the card 30, devices capable of embossing the paper, laser printing or similar. Advantageously, the 100 device of transport of invention cards avoids the presence of scratches on the surface of the paper due to guides that direct the paper, of debris that affect the customization of the card and -7- metal V-rollers do not deteriorate in the presence of heat, for example caused by a heat treatment paper plasma before printing. Preferred forms of have been described implementation of the invention, but of course they are subject to further changes and variations within the scope of the same inventive idea. In In particular, experts in the field will find it clear numerous variants are immediately evident and modifications, functionally equivalent to the previous ones, which fall within the scope of protection of the invention as highlighted in the attached claims in which, if any reference marks placed in brackets are not can be interpreted as limiting the claims themselves. Furthermore, the word "comprising" does not exclude the presence of elements and / or phases other than those listed in the claims. The article "un", "one" or "una" preceding an element does not exclude the presence of a plurality of such elements. The simple fact that some features are mentioned in different dependent claims between them indicates that a combination of these characteristics cannot be advantageously -8- used. -9-
